5. Study Description

Brief Summary
The investigators hypothesized that an ultrasound-guided lung recruitment maneuvers would be more effective in preventing postoperative atelectasis than conventional alveolar recruitment after surgical correction of idiopathic adolescent scoliosis.
Detailed Description
In anesthetized children, the incidence of lung collapse with episodes of hypoxemia is high. Diaphragm dysfunction induced by general anesthesia is one of the most important factors in the genesis of regional losses of lung aeration; the mass of the abdominal organs pushes the diaphragm cranially compressing the lungs in the most dependent areas. Such regional lung collapse may range from slight loss of aeration to complete atelectasis. Scoliosis correction surgery for adolescent idiopathic scoliosis (AIS) is effective in preventing deterioration of lung function caused by disease progression, and improving lung volume over the long term. However, complications of the respiratory system and pulmonary dysfunction may occur in the immediate postoperative period. General anesthesia (GA) and positive pressure ventilation can cause decreased lung volumes, expiratory flow rates, and oxygenation after surgery as a result of positive pressure ventilation, partial recovery of respiratory muscle, pain, and immobilization. Lung ultrasound has been gaining consensus as a noninvasive, radiation-free tool for diagnosing various pulmonary diseases in adult and pediatric patients. Evidence supporting lung ultrasound use is expanding beyond emergency and critical care settings to perioperative care. It has been reported that lung ultrasound (LUS) at a patient's bedside immediately following surgery can be useful for diagnosing respiratory complications. LUS has proven to be a valuable bedside diagnostic tool for pneumothorax, with high sensitivity and specificity (78.6% and 98.4%, respectively), and a higher rate of detecting abnormalities such as lung alveolar consolidation and pleural effusion than bedside chest X-ray or physical examination. LUS has also been used to diagnose anesthesia-induced atelectasis in pediatric patients.

Arm Type
Active Comparator
Intervention Type
Procedure
Intervention Name(s)
conventional lung recruitment
Intervention Description
The recruitment maneuver will be performed by pressure controlled mode maintaining a steady airway pressure of 15 cmH2O, with 5 cmH2O increments in PEEP until a peak pressure of 30 cmH2O will be achieved. Each PEEP level will be maintained for 5 sec. The peak airway pressure will be maintained for 10 sec or five breaths and subsequently reduced, followed by maintenance with the previous ventilator settings.
Intervention Type
Procedure
Intervention Name(s)
ultrasound- guided lung recruitment
Intervention Description
The recruitment maneuver will be performed under ultrasound guidance until no collapsed lung area was visible. The strategy to increase the airway pressure will be the same as that for the conventional maneuver, although the maximal pressure limit was 40 cmH2O.
Primary Outcome Measure Information:
Title

the incidence of postoperative atelectasis in post-anaesthesia care unit
